Abstract
A numerical method, based on the standard matrix formulation of the electric field integral equation (EFIE) for calculating the scattering from conducting bodies near resonant frequencies, is given for both stabilizing the numerical calculations and finding the form of the resonant fields. When this method is used along with a direct solution to the original matrix equation, it requires insignificant additional computation. An additional advantage of this approach is that it can easily be implemented in existing computer codes by using a single, standard but general, plug-in module.Keywords
